In this study biogeochemical export in a set of catchments that vary from 6ha to almost 1500ha is investigated. Studying catchments across this large range of scales enables us to investigate the scale dependence and fundamental processes controlling catchment biogeochemical export that would not have been possible with a more limited data set. The Devil Canyon catchment, in the San Bernardino ...

We address the problem of end-to-end visual storytelling. Given a photo album, our model first selects the most representative (summary) photos, and then composes a natural language story for the album. For this task, we make use of the Visual Storytelling dataset and a model composed of three hierarchically-attentive Recurrent Neural Nets (RNNs) to: encode the album photos, select representati...

This paper examines the interrelationship between music blog buzz and album sales, examining both time precedence and the contemporaneous relationship between the two. Using the Granger Causality methodology to examine time precedence, we find evidence of bi-directional causality for the full sample of music albums we are examining as well as for both independently released and major-label rele...

Water originating from coal-bed natural gas (CBNG) production wells typically contains ammonium and is often disposed via discharge to ephemeral channels. A study conducted in the Powder River Basin, Wyoming, documented downstream changes in CBNG water composition, emphasizing nitrogen-cycling processes and the fate of ammonium. Dissolved ammonium concentrations from 19 CBNG discharge points ra...

Spaţiile virtuale 3D devin din ce în ce mai mult utilizate, de la jocuri până la aplicaţii industriale, medicale, militare sau ştiinţifice. Unele dintre cele mai importante aplicaţii ale acestora sunt în e-learning şi edutainment. Lucrarea de faţă prezintă elementele constitutive şi aspecte ale creării unui”muzeu virtual 3D”, pornind de la experienţa autorilor în dezvoltarea aplicaţiei software...

Ethanolic and aqueous extracts from five plant species used in Turkish traditional medicine were evaluated for in vivo hypercholesterolaemic and antioxidant activities: Agrostemma githago L., Potentilla reptans L., Thymbra spicata var. spicata L., Urtica dioica L. and Viscum album var. album L. We assayed the effects of the administration of plant extracts on serum total cholesterol, triglyceri...

Conceptual modelling has changed over years. Database applications form an integral part of most computational infrastructures. Applications are developed, changed and integrated by specialists in conceptual modelling, by computer engineers, or by people who do not have sufficient related background knowledge. Conceptual databases models are everywhere in applications and are likely to interfer...

Purpose The explosive growth in computer power over the past several decades offers new tools and opportunities for economists. Volume 1 of the Handbook of Computational Economics (Amman et al. 1996) surveyed the growing literature on computational methods for solving standard economic models such as Arrow-Debreu-McKenzie general equilibrium models and rational expectations models. This second ...
